“…In some case studies, authors choose to apply computational, intelligence-based algorithms to reach a degree of automatic advising by combining genetic algorithms with decision trees for developing the short-term curricular schedule, as well as by combining perception marks with the registered courses [41] or by assisting in data mining and intelligent adaptive fuzzy logic for implementing an elective course suggestion system [44]. In paper [37], the authors present recommendations of student courses using ant colony optimization and concluded that their solution is promising, since it overcomes most of the disadvantages of classical approaches based on collaborative filtering in terms of performance. AAS proposed in [24] employ recommendations based on decision support tools, while other authors [33,34], use expert systems combined with semantic infostructures [22,28,47], or database management systems [6].…”
